The wall form reinforcing system generally comprises a plurality of wall form reinforcing frames distributed along the height direction of the wall so as to reinforce the template by hooping the vertically arranged wall form back edges. The existing reinforcing bars are usually made of channel steel type materials, so that a wall formwork reinforcing system usually needs to adopt a double-layer reinforcing bar structure, a certain distance is reserved between two layers of reinforcing bars, the two layers of reinforcing bars are welded together through connecting members, adjacent cross bars form a polygonal closed reinforcing frame through right-angle members and angle split assemblies, and split bolts of the angle split assemblies penetrate through the two layers of reinforcing bars. Therefore, although the structural strength and the reinforcing effect of the reinforcing frame are ideal, the reinforcing frame is large and heavy due to the adoption of the double-layer reinforcing bars. And because the length specification of the section bar is usually the sizing, when the length of the wall surface is greater than the length specification of the section bar, the section bar needs to be lengthened by welding to form a reinforcing bar corresponding to the length of the wall surface. This lengthening method does not facilitate the recycling of the profiles. For this reason, further improvement of related components of the existing wall form reinforcement system is required, so that it is desirable to obtain a horizontal bar type reinforcement system having light weight and relatively small structural size, so as to satisfy reinforcement strength while facilitating recycling.
